Byrna SS61301 12 Gauge Slug

A: Hi Thomas, this can be used in shotguns with 2.75" or 3" chamber. The 12 gauge rounds work with standard cylinder bore and improved choke shotguns only. The 12 gauge rounds were designed to work in a pump action or single shot shotgun and will not cycle a semi automatic shotgun as they do not contain gunpowder. They can be manually cycled and fired through most semi auto shotguns. Stay safe & have a great day!
